Anyone know why there are two air switches on the air brake master cylinder and two separate brake sense wires?

The brake system is a dual system.

One tank can be damaged and the other air system, thru control valves, will supply air to all brakes.

If they only had one brake light switch, it would not cover both systems, in the event of a failure.

thanks ive have a short in my brake lights that keeps blowing the fuse, and sometimes the 4 way flashers. Ive tried everything and yesterday I disconnected on brake switch and it blew and disconnned it and plugged in the other and it hasn't blown yet, not sure if the switch is the problem.

Leave it off for now, time will tell.
